Frequently Asked Questions
re the live broadcast Video Streaming Solution VSS-1:
Don't the Polycom, LifeSize, Tandberg and Sony
videoconferencing systems . . . already
support streaming?
- Not over the web and not
in Windows Media player . . . Streaming on the
Polycom and
the Tandberg line
normally works only on LAN's with Apple QuickTime Player
and Cisco IP/TV viewer (and not the popular
Windows Media Player).
- Both the Polycom
streaming and Tabdberg streaming function is based just on International
Telecommunication Standards H.261 and G.711. This does not provide
streaming over the web.
- See info on Tandberg
streaming capabilities at:
http://www.tandberg.net/collateral/product_brochures/TANDBERG_streaming.pdf
- Polycom says. . ."In general, streaming using IP multicast
does not work across the Internet. It is usually restricted to a local
area network (LAN). This is because most routers on the Internet do not
pass multicast data. To stream to someone on the Internet, the person's
unicast address must be specified."
- For multicast streaming
on your LAN you can specify the number of router hops usually set to
just 1 or 2.
- In contrast our
VSS Video Streaming Solution works with Media
Player and can broadcast over the internet to an unlimited number of
viewers.
Can this VSS-1 system work with any type of Polycom,
LifeSize, Sony or Tandberg system?
- Yes. It works well with almost any model. It uses the dedicated VCR/DVD
recording connections on these systems to stream out and record both the
local and the remote audio and video.
Can the live video from the VSS-1 be saved for later playback
locally and playback over the web?
- Yes. Archived streams can easily be saved for
each session and they can be made available for on-demand access. The VSS
system includes optional giga-bytes of on-line storage and bandwidth with the low
cost annual ISP service. The archived streams are saved in the popular
Windows Media format.
What does each person need to see the live stream?
- The client just needs appropriate speed internet
access and the popular Microsoft Windows Media Player - available for free
download from
http://www.microsoft.com/windows/windowsmedia/download/ (this link
also describes the PC requirements and the installation instructions).
